Mergescreens Avis 

I purchased a Merge Screens/Aucar large‑screen CarPlay unit for my 2014 Audi A7 and had it installed by a professional Audi aftermarket shop. The experience was extremely disappointing.

The first unit never worked correctly. Merge Screens and Aucar support eventually decided a part was defective and said they would send a replacement. It took roughly two weeks to get that part, with conflicting information about when it was actually handed over to DHL and an additional import fee charged to me. The part that arrived was labeled for an Audi A6, and I was told “A6 and A7 are the same.”

After the replacement box was installed, the system briefly worked (MMI controls and CarPlay audio) and then failed again the next day with a black screen and dead MMI controls—the same symptoms as the original unit. My installer verified wiring, power, and fuses, and repeatedly asked for harness pin‑out diagrams. Support responses were slow (including a Chinese New Year delay) and mostly limited to “check the fuse,” “reconnect all plugs,” and speculation that “the motherboard may have burned out,” without providing detailed technical documentation.

Eventually Merge Screens admitted that the only option they could offer was to return the unit for a refund and that “a new unit will not solve the issues, until we get to the bottom of it.” I did receive a refund for the device, but I was left with a $1,250 bill from the installer for the initial install, repeated troubleshooting, removal of the defective unit, and re‑installation of my original Audi parts. The installer did his job and spent significant time trying to make a clearly problematic product work.

In my opinion, this product did not perform as advertised, and the support process was slow, inconsistent, and ultimately unable to resolve the problems. I would not recommend Merge Screens for Audi A7 owners, especially if your car is a daily driver and you cannot afford weeks of downtime and unpaid extra labor chasing defective hardware.

I have a 18 ram 2500 with alpine factory system. I've been in contact and what they suggested to do made the issues worse. I actually found certain settings that actually work after several hours of trying on my own. My truck originally came with uc4, I upgraded to uc 5 and have 2 12 subs running on a crossover designed to work with vehicles with factory subs to allow for an independent amp to power the aftermarket subs. With their supposed tech support, laughable at best. After their little scheduled video call, I know things will still not work and been demanding a refund. The concept is nice but when it comes to real world practicality, don't bother, don't waste the time.

I’ve experienced such horrible service from this company. The screen didn’t work as intended / advertised. It’s been a nightmare to get my replacement screen. Which I still do not have & no precise date on when I’ll ever receive it. The communication is trash and no one follows through when you call for assistance. Just more run around & another unprofessional unhelpful person with an attitude.
